What's Changed

Flow-label configuration status for EVPN ELAN services. The output for the show evpn instance extensive command now displays the flow-label and flow-label-static operational status for a device and not for the routing instances. A device with flow-label enabled supports flow-aware transport (FAT) flow labels and advertises its support to its neighbors. A device with flow-label-static enabled supports FAT flow labels but does not advertise its capabilities.

Instance type change is not permitted from default to L3VRF in open configuration (ACX Series, EX Series, MX Series, QFX Series, SRX Series, vMX, and vSRX)–DEFAULT_INSTANCE is the primary instance that runs when there is no specific instance type configured in the route <codeph>set routing-options?<codeph>. Any instance you explicitly configure is translated into set routing-instance r1 routing-options?. The issue appears in translation, when you change instance type DEFAULT_INSTANCE (any instance to DEFAULT_INSTANCE) to L3VRF or L3VRF to DEFAULT_INSTANCE. As a result, such changes are not permitted. Additionally, DEFAULT_INSTANCE can only be named DEFAULT, and DEFAULT is reserved for DEFAULT_INSTANCE, therefore allowing no such changes.

Junos YANG modules for RPCs include the junos:command extension statement (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The Junos YANG modules that define RPCs for operational mode commands include the junos:command extension statement in schemas emitted with extensions. The statement defines the CLI command for the corresponding RPC. The Juniper yang GitHub repository stores the RPC schemas with extensions in the rpc-with-extensions directory for the given release and device family. Additionally, when you configure the emit-extensions statement at the [edit system services netconf yang-modules] hierarchy level and generate the YANG schemas on the local device, the YANG modules for RPCs include the junos:command extension statement.

Changes to the JSON encoding of configuration data for YANG leaf nodes of type identityref (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—If a YANG leaf node is type identityref, Junos devices emit the namespace-qualified form of the identity in the JSON encoding of that node. In addition, Junos devices accept both the simple (no namespace) and the namespace-qualified form of an identity in JSON configuration data. In earlier releases, Junos devices only emit and accept the simple form of an identity. Emitting and accepting the namespace-qualified identity ensures that the device can properly resolve the value in the event that the YANG data model defines an identity and a leaf node containing the identifyref value in different modules.

The file copy command supports only text-formatted output in the CLI (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The file copy command does not emit output when the operation is successful and supports only text-formatted output when an error occurs. The file copy command does not support using the | display xml filter or the | display json filter to display command output in XML or JSON format in any release. We've removed these options from the CLI.
